This grant supports the research program of the experimental nuclear physics laboratory at Florida State University. The laboratory includes a superconducting linear accelerator and an FN tandem Van de Graaff accelerator injector. The research of the laboratory lies in six main areas. The macroscopic properties of nuclear reactions with heavy ions are studied through inclusive and coincidence measurements of fusion, fission, breakup, and incomplete fusion reactions. High resolution resonant particle decay spectroscopy is applied to studies of selected high spin, high excitation energy states. The interaction of collective and single.particle excitations is examined in f.p.g shell nuclei using gamma.gamma and multiparticle.gamma coincidence techniques. Spin dependent effects in reactions, including asearch for a spin orbit force, will be carried out using reactions induced by beams of polarized lithium.6 and lithium.7. The effects of angular momentum on octupole excitations will be pursued experimentally using a variety of techniques. Collaborative research at CEBAF, Argonne and other laboratories is also conducted, as is collaborative research with outside users of the Florida State University accelerators. In addition, ongoing projects to construct an optically pumped polarized ion source, and a large solid.angle Bragg curve spectrometer will be completed.

这笔赠款支持佛罗里达州立大学实验核物理实验室的研究计划。该实验室包括超导直线加速器和FN串联式范德格拉夫加速器注入器。该实验室的研究主要集中在六个方面。通过聚变、裂变、裂解和不完全聚变反应的包合测量和符合测量，研究了重离子核反应的宏观性质。高分辨率共振粒子衰变光谱被用来研究选定的高自旋、高激发能态。用伽马-伽马和多粒子-伽马符合技术研究了f.p.g壳核中集体和单粒子激发的相互作用。反应中的自旋相关效应，包括寻找自旋轨道力，将利用极化锂和锂的束流引起的反应来实现。角动量对八极激发的影响将通过各种技术进行实验研究。在CEBAF、Argonne和其他实验室也进行了协作研究，与佛罗里达州立大学加速器的外部用户进行了协作研究。此外，正在进行的建造光泵偏振离子源和大立体角布拉格曲线光谱仪的项目将完成。
